One-Call Mapping Notification Processes



One-Call Mapping Notification Processes

Alabama One-Call (ALLC)

They notify based on polygon only, and place a 100 meter buffer around the digsite.

Arizona One-Call (ABS)

The tools used within the service area application.  When drawing the excavator dig site shape the person creating the ticket can use a variety of shape tools; 1) A (dot) that is a set radius of 200 ft, 2) An (oval) that is an adjustable radius but has a minimum size of 200 ft, 3) A rectangular/square polygon shape adjustable shape but has a minimum size of 400 X400 ft, 4) A line drawing tool that is great for following roadways or creating paths; this drawing tool considers the drawn line as the center line of path and then adds a  200 ft buffer either side of the line; 5) And quarter sections or entire sections can be selected for notification.

Arkansas One-Call (AOCALL)

Utilities are notified based on the polygon they submit.  The CSR will mark on a digital map based on the information that a caller gives. They then place a 300' buffer around that dig site, if the utility’s buffer is close enough to that dig site with the buffer they may be notified.  All their system is doing is a basic drill down and if the utility’s area is caught in the drill down then they may be notified.  That being said, sometimes the CSR will mark a rather large area to be notified base on the caller sometimes not knowing where he or she is truly at. 

California North and Nevada One-Call (USAN)

They notify their members based on the CSRs mapping of the dig site.  Their CSRs use the same tools the members use when mapping out their service area.  The dig site that is drawn by the CSR overlays any service areas that is registered and that is how the system knows which members to send the ticket to.  Everything is based off of polygon and they always put a buffer around a dig site.  The default buffer for a dig site is 400ft, but a CSR may create a larger buffer depending on the dig site location. The max size for a notification area is 3 miles in the county/rural areas and 1 ½ miles in the city limits.

California South One-Call (USAS)

They notify by Thomas Guide grids, each grid broken down into 1/4 mi quads. The dig location is drawn with a polygon that has a 150ft buffer.  If the utility uses polygons for notification and the dig site/buffer touches the utility polygon, the utility receives the ticket.  If the utility is notified by grids and the dig site drawing falls within one of the grids in the requested notification area, the utility would receive the ticket.

Colorado One-Call (UNCC)

They attempt to use polygonal drawing tools on each and every request and apply a minimum of a 250ft buffer on all linear shapes drawn on the map, (areas drawn are not buffered). They sometimes revert to selecting quarter section(s) if the caller doesn’t have sufficient information or if they don’t have the landBase in our map to support narrowing down the notification to a polygon. Every time a polygon is drawn on the map, the system automatically adds the quarter section behind it and the polygon members are only notified if their shapes touch the drawn shape on the map, but the members that have not redefined are notified based on the quarter section.

If they cannot draw a shape and use only the quarter section then all members within that quarter section, (grid and polygon) are notified if their database touches the selected quarter section.

Connecticut One-Call (CBYD)

It's based upon the intersection of the member polygon(s) and the polygon created for the street segment the dig location is on.  A street segment is generally set up in 100 blocks; e.g. 1-99 Main St, or 100-199 Main St. at CBYD.  So if the excavator calls in 35 Main St, then 1-99 Main St would be the selected street segment which would be buffered. The Dig Location Buffer is set at 133 feet, but Brian Wegner was not 100% sure since each Board of Directors makes that determination.

Florida One-Call (SUN)

It depends on the method used to select the dig site. For example, if an ITE user selects a ¼ minute as his dig site, the member will receive that ticket if ANY of their service area is within the selected grid. The excavator either calls in the ticket or can create them online if they are an ITE user. This is the only way they can create a ticket. The excavator can choose the grids or the computer usually chooses them if the address or intersection or between intersections come up in the system and if the utility service area touches ANY part of it they will receive the ticket.

Georgia One-Call (UPCA)

Add 200ft buffer around dig site. If digsite touches our polygon, we receive the ticket.

Idaho One-Call (PWI)

CSR draws dig site related to address range given. If dig site touches utility polygon, the utility receives the tickets. No additional buffer added.

Illinois One-Call (JULIE)

For new tickets and any subsequent tickets from these new tickets, they do the following. For old tickets (before polygon or before a polygon change), if the member got the ticket before they will get it again, unless an operator removes them from the ticket

1. A dig site can be located on the map. They are @ 75% of tickets being mapped system wide, but that number will go up as they get better street data and finish training their web user, which account for 40% of their ticket volume.

a. A dig site is located by their operators.

b. That site is then buffered by their buffer distance, which varies by county according to the street centerline accuracy. Currently they have 71 counties with a 150 ft buffer and the rest are at 300 ft. As soon as they get better county data they put it on their system and lower the buffer to match.

2. A dig site can not be located on the map

a. The operator locates the grid(s) rather than an actual spot

b. The member gets notified if their polygon touches any part of a grid that was turned on to make sure they don’t miss any tickets

c. The member gets a grid tickets only if they have that place in their database

3. A place ticket is called in. Very few tickets go by place

a. Very few ticket go out by place

b. The member gets a place ticket only if they have that place in their database

Illinois Diggers One-Call (CUAN)

The facility has a buffer (rectangle) placed around it in an effort to identify any construction activity within and around the actual fiber.  The notification process and how the system determines whether or not a utility gets a ticket is based on this buffer (rectangular) system.  If construction activity falls in a rectangle where the facility exists, a ticket is generated and transmitted to the utility. The buffer around the facility is usually by city block, which is around 660ft.

Indiana One-Call (IUPPS)

If the CSR draws the digsite, there is no additional buffer added. If the computer generates the digsite, an additional 200ft buffer is added.

They list the grids the digsite polygon touches on the tickets. They use address range data for mapping, and create their digsite polygon off the address range available (ex: a bridge may have mile digsite because there are no addresses given). They are looking to move towards using parcel data so digsites will be reduced in the future.

Iowa One-Call (UPLS)

Iowa One Call Systems recently introduced an innovation to provide our customers with four times greater control over their coverage area. Our grids which were approximately 900 X 1200 ft, are now approximately 450 X 600 ft. Each grid that you knew in your former record count is now equal to 4 grids. So, even if you've reduced coverage in an update, you may notice a substantially greater grid count overall. Their CSR's try to grid as little as possible, while making sure they always include the entire dig site within the grids selected.   Procedure does not require the CSR's to select any additional buffer around site, but again, ENTIRE dig site must be within grids selected.

Kansas One-Call (KOCS)

Notify off of polygon only. No additional buffer.

Kentucky One-Call (KUPI)

Kentucky 811 uses both polygons and grids to map the dig site.  The agents rarely use the grid tool.  If this tool is used to select a dig site it is usually done by someone using web ticket entry.  You can tell if it is a ticket entered over the web by the operator name listed at the top of the ticket.  Web ticket entry users will have a “.” in the middle of their name (ex: JILL.ROBERTS). The only time a 200’ buffer would be applied is when the agent maps using the linear or the pin point tool.  The linear tool would be used in cases of digging along roads and streams and the pin point tool would be used for intersections or fire hydrants.

Louisiana One-Call (LOCS)

Operators will ask the caller for a street address of the worksite along with a street that intersects the street they are doing the work on that is closest to that address. The operator will map the locate based off of this information by mapping one street forward and one street back from the intersecting street the caller has given in order to allow for possible misinformation by the caller. In general the operator will map along the road on both sides for at least 50 to 100ft into property unless otherwise stated by the caller. The exception to this would be locates that do not have addresses, that are off no name roads or those that are along a pipeline or at a wellsite. In those cases, the operator will ask the caller to give the approximate distance and direction to the worksite from 2 streets that intersect closest to the worksite and proceed with mapping the ticket according the information given by the caller. The operators are not able to see the database maps of the members when they are mapping a ticket, nor will they know if a company should or should not be notified if it's not listed or listed on the back of the ticket once they are through mapping. They will simply have a list of those companies that have polygons that touch the map that they have just drawn and they will give the caller the opportunity to hear that list of companies to verify who will be notified. If the caller states that a company is missing off of the list of companies notified, the operator will advise them to call that company directly to report their digging so that company will be aware of areas they are missing locates in and will have the chance to make database changes as needed.

MASDIG (RI, NH, ME, VT, MA) One-Call

At Dig Safe they use the entire length of the street throughout a town as their dig location.  I.E. call in 35 Main St, then every street segment named Main St will be selected in the town in which the excavator is digging, except in cases where they give a street intersection.  Intersections are more precise with Dig Safe since they would only buffer the point of the intersection.  It's not as precise, but that is what their Utility board wants.  **They add 500ft from the center line of the street given or to the dig site given in all states.  

Michigan One-Call (MISDIG)

Members have 3 notification options; a. Grid (grid size ¼ X ¼ minute of latitude & longitude, b. Polygon (buffered by member), c. Place level (Member will receive all tickets designated by the “place” names (City, Township or Village) listed in their database. Any 1 or a combination of the 3 can be used by a member. Most tickets sent by MISS DIG will have grid and polygon information displayed on the delivered ticket. However, some tickets are sent at a “place level” (without grid/polygon). Member receipt of “place level” tickets is dependent upon the member having the County and Place names listed in their database. The current release of the ticket entry program allows the creator of the ticket to draw an un-buffered polygon around the proposed work area. A newer version being released shortly will implement a minimum 250 foot buffer when drawing the polygon on the ticket.

Minnesota One-Call (GSOC)

The member database is made of up polygons and there is no extended buffer beyond the shape of them. When it comes to the mapping portion of their ticket taking process, their operators will draw what they call an “excavation polygon” that should cover the entire dig site and is drawn based on the information they receive from the person requesting the locate. If the drawn “excavation polygon” touches one or more utility database polygons in any way, shape or form, the utility will receive notification of the request. If the drawn “excavation polygon” does not touch the utility database polygon, they will NOT be notified.

Mississippi One-Call (CALLMISS)

They mark a dig site with either a point, line or polygon.  These tools have a built in 300 foot buffer around them.  If a dig site is touching the company’s service area or is within 300 feet or less of the service area our company will be notified.

Missouri One-Call (MOCS)

They place the company's polygons on a hidden layer on their base maps.  When a person calls into the call center, the operator draws a box on the map around the dig site with the information provided by the caller.  If the locate polygon somehow touches/crosses the company's polygon, we get the ticket.

MISUTIL

For Western Shore MD and DC:

- We use grids from the ADC maps for Member Notification

- The grid(s) in which the excavation site is in are entered into the ticket.

For Eastern Shore MD and DE:

- We use polygons for Member Notification

- We do not place a buffer around the polygons. If the area we use on the map touches your polygon, you will be notified.

Montana One-Call (UULC)

They have a base map that they use to find all the worksites where the callers are doing their work. Overlaid on that basemap is the coverage area for all the various member utilities. When their operators draw in the boundaries of the digsite, their system will check to see which utilities have coverage that partially/wholly are within or overlap that area and the system generates a notification to them. The coverage areas can be any size and shape that is needed. If a company wants their boundaries to conform to the Township/Range/Section grids, then that is ok, but most choose to use polygon based coverage. As a rule, there is no buffer added to the digsite, but occasionally they will have to include a much larger area than they would normally need to. If a caller tells them they are 1/2Mile from the intersection, but can't tell them which direction, then they are required to go 1/2Mile in all directions. Or if it's an extremely new area that isn't on the maps, they may be required to use 4 older streets to kind of box it in. Other than that, they mark out the worksite as the caller describes it.

Nebraska One-Call (DHON)

When a contractor calls and gives them an address or an intersection, their operators enter all the information and then go to the map. It will map the area with an additional 250 ft buffer of the address or intersection/dig site given. If the call says he is going farther that add the distance to the map. Some of their members have there data entered by TRSQ and some by polygon. If the additional buffer on the dig site touches their registration, they receive the ticket. Or in other words, all the member information is in layers and when our address or intersection is mapped and touches any of the layers that member is notified.

New Jersey One-Call (GSUPLS)

They use a grid-based notification within the NJOC System. In New Jersey, a 1/16th minute lat/long grid is used. Depending on where the grid is in the state with it being based upon lat/long lines it is approximately a 300 ft by 400 ft grid. Exclusion can also be provided based upon the County/Municipality if needed. An example of using this type of exclusion would be if a portion of a grid extends into a neighboring municipality where you do not own, operate, or control any underground facilities and would like to avoid notification in the neighboring municipality. The grids determined on the ticket by one of three methods at this time: 1) Automatic grid look-up based upon the address range or intersection on the ticket, 2) Manual selection of grids by our Customer Service Representative taking the call based upon instructions provided by the caller, and 3) Manual selection of grids by an excavator using remote ticket entry software.

New Mexico One-Call (NMOC)

A member coverage layer can look like anything and be based on any information.  So, if a layer is based on Twnship and Rng then one would see a pattern made up of squares and that would cause a notification if anything were to happen anywhere in that whole quartersection. The ticket can be created a few ways.  If the ticket is based on a streets search then any part of the street segments that were selected would have to intersect the member layer in order for the member to be notified. If the ticket was based on a map selection that the operator made, either due to the fact that there are no roads in the area or that the ticket is a wide area locate and includes the entire project size which could be from 30 acres to 30 miles large or more, then any member layer that has any piece of coverage within the polygon that the operator creates will cause a notification. If an excavator refers to a quartersection on the ticket, they automatically create a map selection in that quarter.  Otherwise the streets search is used.

New York One-Call (UFPO)

Their system has a 200ft to 400ft buffer automatically built in, depending on the type of polygon that is drawn by the CSR. They notify based on the dig site that the excavator provides and by the member polygon selections. Please note: They ask the Excavator for two cross roads that the dig site sits between, if the excavator cannot give them the two roads, they notify the whole length of the road for the specific "town, city, or village" the dig site is in. They also have some members that use the 1/4 mile square grids. Again it is all based on the dig site and how it touches the member’s service area mapping.

New York City One-Call (NYC)

They place the company's polygons on a hidden layer on their base maps.  When a person calls into the call center, the operator draws a box on the map around the dig site with the information provided by the caller.  If the locate polygon somehow touches/crosses the company's polygon, we get the ticket.

North Carolina One-Call (NCOC)

Tickets entered over the web on the Ocars Pro Remote Ticket Entry only allow the user to grid the locate area with the ¼ mile grids.  Tickets taken on the Newtin Remote Ticket Entry allows the user to polygon the dig site. Based upon the information given on the ticket the system will look at the different databases in this order: Grids/Gridlets, Places, Counties, Ungridded Streets and then Polygons. The Newtin system allows for the CSR and Remote Ticket Entry user to put a dig site polygon around the location (be it an intersection, a line down the road, or a specified shape) which has an automatic 250ft buffer.  Neither the CSR nor the RTE user can change this buffer size.  At this point in time there are still many companies that are using the Ocars Pro Remote Ticket Entry which will only allow them to select grids to define the location area.  It is the goal of the RTE Department to have all users trained and using Newtin Remote Ticket Entry by December 1st of 2007. 

North Dakota One-Call (NDOC)

**This is the same as Minnesota. They are in the same office.**

When CSR cannot verify the digsite location on the maps with the excavator, they will notify off the twp/range/sect if the excavator can provide it. They try to go off actual location if possible.

Ohio One-Call (OUPS)

The area of notification (dig site... not a pinpoint area but an area where the dig site is contained) is generated by IRTH's software based on the information available by the caller.  They add a buffer of 200' to the area of notification.  This is done as a safety net to compensate for inaccurate measurements called in.  The utility’s database, whether it is a polygon or grid, must be intersected by the system generated area of notification in order for you to receive a ticket.  Because Sprint is a polygon member, the area in which we would receive tickets is greatly reduced.  This does not mean all the tickets we receive will involve our facilities, but the number of unnecessary tickets we would have received as a grid member will be reduced.  On their tickets there is a bounding box.  It represents the grids affected by the "Dig Site".  This is, to OUPS, rather useless information because it represents an area far greater than the actual area generated on our system.  The bounding box is a carry over from our legacy system.

Oklahoma One-Call (OKIE)

They notify by both quarter section grids and spatially depending on the members registration type. They do not place any buffer around the quarter section method but do place a 200 foot buffer around the spatial member selection. Their spatial members are responsible for the buffer placed around their notification services areas; OKIE recommends 500 feet. Sprint is registered by quarter sections.

Oregon One-Call (OOC)

See Montana

Pennsylvania One-Call (POCS)

Dig site is buffered by 150ft, and they use grids to notify (80ftx110ft). If grid touches the member polygon we would receive the ticket. Member polygon data is converted to grids and if the dig site grids match our polygon grids, we get the ticket.

South Carolina One-Call (PUPS)

They use strictly polygons or buffers.  Currently they have three ways to have a site marker for a notification, depending on what info is given.  Points...which mean something geocoded, lines, and polygons.  They all have 300 foot buffers on the dig site markers.  That may be changing for the polygons soon.

South Dakota One-Call (SDOC)

They use a grid-based notification within the South Dakota One Call System. A 1/8th minute lat/long grid is used. Depending on where the grid is in the state with it being based upon lat/long lines it is approximately a 400 ft by 600 ft grid. The grids determined on the ticket by one of three ways: 

1. Automatic grid look-up based upon the address range or intersection on the ticket, 2. Manual selection of grids by our Customer Service Representative taking the call based upon instructions provided by the caller, or 3. Manual selection of grids by an excavator using remote ticket entry software.

Tennessee One-Call (TNOCS)

When they mark the map, the agent is using a point (GPS), line, or polygon.

They include an invisible 100m (333 ft) buffer for safety. This should not be taken into account when registering the utility database. If the utility falls with the point, line or polygon and/or that 333 ft buffer, the utility will get notified whether they are spatial or grid based. Depending on the buffer, spatial members are typically likely to receive fewer tickets than a grid member just because the database is more accurate and you are not getting over-notified.

Texas One-Call (TESS & TOCS)

TESS uses a gridding system (lat/long or GPS coordinates). Their coordinator marks 1/2mi radius around dig area for rural areas. If the member polygon touches the 1/2mi radius or is within 300ft of the dig site, the member will receive the ticket. For all other areas, if any dig site is within 300ft of the dig site that is drawn by the coordinator, the member will get the ticket. TESS and TOCS share databases. TESS has a system that converts the polygon data to grid data and gives that to TOCS (1/4mi grids). TOCS then uses the grids to notify their members.

Utah One-Call (UTAH)

Notifications are sent to each member based on their individual mapping selections first. If they have both Grids and polygons and the dig area crosses with one of both of the two map selections then it sends the notice.  There are a few rare situations where it does not have a grid or polygon and it defaults to place name. Utah does map 99% of most of our transmissions.

Virginia One-Call (VUPS)

Notification of members is based on the map area they select to be notified in. Members can choose either grids or polygons or a combination of as their notification area. VUPS does not add any buffer to the notification polygons that utilities submit to them unless the utility so requests them to do so. VUPS DPSs use only polygon shapes to create the ticket excavation area and the system will notify any member that has grids or polygons that overlap the excavation polygon. The excavation area has a default minimum size of 50ft. This can be changed depending on the information that the caller provides to the DPS. If the DPS feels that the information does not pinpoint the area, they can increase the size of the excavation area to insure that the dig site is covered.

Washington (UULC, IEUCC, NUNC/WOC)

See Montana

West Virginia One-Call (WVMISS)

They use a grid-based notification in the Miss Utility of West Virginia System. A 1/5th minute lat/long grid is used. Depending on where the grid is in the state with it being based upon lat/long lines it is approximately a 800 ft by 1200 ft grid. The grids determined on the ticket by one of three ways: 

1. Automatic grid look-up based upon the address range or intersection on the ticket, 2. Manual selection of grids by our Customer Service Representative taking the call based upon instructions provided by the caller, or 3. Manual selection of grids by an excavator using remote ticket entry software.

Wisconsin One-Call (DIGGERS)

#1)  Polygon notification - Their call center representatives (CCRs) take information from the excavator and use it to create a worksite polygon.  The member company will receive a locate request if the worksite polygon intersects their polygon database. #2)  Place Name notification - If a member company wants to receive notification for an entire City, Village or Township and they don’t want to maintain a polygon database, they can use Place Name notification.  The member company provides DIGGERS with a place name or list of place names that they use to create their Place Name Notification Database.  Anytime a locate request is filed using any of the place names in their place name database they receive a locate request…no matter where in the City, Village or Township the actual worksite is located.

#3)  A combination of Polygon and Place Name notification - A member company such as a City or Village is most likely to use this method.  They may want to be notified of all excavating in the City or Village limits (Place Name notification) but they also want to receive locate requests for a specific area leading to and including their wastewater treatment facility outside of the City or Village limits. DIGGERS does not use grids.  All of the worksite polygons triggering notification are hand-drawn by the CCRs per the excavator’s unique instruction.  It is pretty safe to say that a worksite polygon is a unique shape per locate request.

Wyoming One-Call (OCW)

The One-Call of Wyoming System utilizes two different "grid" platforms for its mark out notifications. The "grid" can be defined by latitude-longitude intersecting lines to form a rectangle which measures approximately 880ft X 1200ft. The "grid" can also be defined by the nomenclature known as TRSQ, (Township, Range, Section, Quarter Section), where each quarter section measures approximately 2640ft X 2640ft (1/2 mile X 1/2 mile). Wyoming mark-out requestors can and do, supply the broader range TRSQ information when placing requests for facility locates. The facility owner can choose either platform for protecting their assets, while the two platforms interact appropriately with respect to the "grid" information provided for each mark out request. In any case an additional buffer is not applied around the digsite before notifying the utilities on automatic computer generated lookups. However, the CSR's have the ability to select whatever grids seem appropriate to the dig location if and when the automatic computer lookup does not occur or when the extent of work would exceed the boundaries of permitting an auto-lookup to occur.
